IMPROVEMAAE'NT m WATER-CLOSET VALVES.

Specification forming part of Letters Patent No. I369, dated January 19, 1864.

same, reference being to the accompanying drawings, and the letters of reference thereon.

The object of. my invention is to provide fora water-closet a cock for supplying thejwat'er to the closet, which cock shall be closed by the pressure of thewater flowing through it, and at the same time regulating or retarding the closing of the valve, so as to insure a proper supply of water to the pan after the handle is dropped by combining with it my variable chamber, while the valve, when having been opened by the force applied to tip the pan,

shall remain open till closed by the forceot -water flowing through it, and avoid all extraneous forces capable of closing the valve without the action of the water.

To enable others who may be skilled in the art of manufacturing such articles to make anduse my improvement, I proceed to describe the same.

Thedrawings, Figure 1 illustrates the valvechamber A, having-an inlet and an outlet, between which is arranged the valve-opening or valve-seat S, having its valve R and stem D extending longitudinally with the chamber. At one end of the stem, or otherwise within, the chamber described, is arranged my gov erning-chamber, Z, which is formed by screwing an india-rubber diaphragm, H, thereto and confining the diaphragm by the edge to one end of the valve-chamber by screw-cap 0, thus forming a bellows or expanding-and-contracting chamber, having a small leak-passage into or out of it, as a drilled hole, M, or any other contracted passage, admitting fluid to pass through, through which leak or hole only can the chamber fill. I provide a larger orifice or outlet, L, through which the chamber Z may be rapidly discharged, and provide a valve which will close the latter discharge when the main discharge or flow of water is to be stopped. I employ a rubber band, K, for the valve, to close the said larger orifice;

Other modifications of valvev'ari'ously constrncted and arranged will answer the purnose required.

' I close the opposite end of the chamber also with a rubber diaphragm, E, securing the .edge by the screw-standard or base-nut B. The stem of the valve extends through the said diaphragm, properly secured to the stem by nuts G, as shown,vthe stem also extending through the base-screw or standardnut B for the water against the first-described diaphram, H,will tend to hold the valve from closing till water can enter into the regulatingchamber Z, and thus distend it asthe valve is moved toward its seat, while the pressure of the water against the latterdescribed diaphragm,E,will force or draw the valve gradually to close upon the seat more or less rapidly in proportion to the size of the opening M, or other leak-passage admitting water into the regulating-chamber Z.

The communications leading either outv of or into the regulating-chamber may be constructed and arranged as here described,or in any other suitable way, so as the described purpose is. attained-that is, to retard the motion of the closing of the valve. By making the induction or supply way larger than the eduction-way will secure a greater pressure against the latter-described diaphragm, E, to close the valve, and for this purpose I use a flexible or self-adjusting obstruction, Fig, 9, placed in the eduction-way, so as to secure a proper pressure of water to close the valve, however diminished thesu'pply of water may be, so that it is supplied under a proper head. For this purpose I use a rubber washer, Fig. 9, placed in the outlet-coupling nut, having cross-slits in it, which will open by the pressure of water, but, tending always to assume a closed position, will insure a proper pressure against the diaphragm employed to close the valve, as shown herein.

C'Ihe small passage M only into regulatingchamber Z might answer, provided it were not desirable to open the pan of a closet rap idly. The regulating-chamber Z may be so provided with its discharge-passage as that it shall retain the closing of the main valve while either distending or discharging, or both.

tion and accomplish the purpose described, it

being so connected to the parts of the closet that the valve shall be opened by the lifting of the closet-handle and retarded from closing quickly by the use of the regulating-chamber, (however arranged,) while the valve is (upon dropping the handle) left free to be closed entirel y by the action of the water therein;

I do not now desire to be understood as claiming the broad principle of eflecting and controlling the closing of valves by waterpressnre; but,

Having thus described my invention, what I claim as new therein, and desire to secure by Letters Patent, is-

Combining with a pan water-closet a supply-valve, R, for admitting water into a pan, balancing-diaphragms E H, and a regulatingchamber, Z, for controlling the motion of the valve, the whole being constructed and arranged substantially as showngin Fig. 1 of the accompanying drawings, and for the purposes,

described.
